Be it known that I, R'UaoLr Ely-ria, in"the county of Lorain and r 6 1mm,"? c tizen of the United States, residing; atflute of.,Ol1'io, have invented certain new and useful Improvements in Kettles; and I. do here- .decl'a'rethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itnappertains to make and :use the My; invention relates to improvements in kettles. and a more, "particularly to kettles which are enameled, and which quently made of cast iron. [One of the ,objects f my are freinvention is to provide means for connecting the kettle to the, jacket, without placing undue strain upon the enamelor the enameled portion of the kettle, thereby avoiding cracking or breaking the same. j

' This andwother objects of my invention and theinvention itself will be better undeistoodfrom a descripiton of an embodiw '5 f top plan View of the kettle.

Referring now to the drawing and to the embodiment of my invention shown thereof any suitable shape, being shown in the same. Openings the jacketwall, through which matter may surface the edge of the kettle, as shown at 11.

At 8 is shown the a kettle which may likewise be suitably shaped, being here shown as substantially vhemispherical. 1 At 9 is shown the enamel on the inside of the kettle extending over the thereof andover the flange 10 on At is shown one portion of the means for connecting, the kettle to the jacket.- In

the embodiment shown, the member 15 consists of a flange extending around the top edge 16 of the kettle; I prefer to make, the Q 55 flange integraliwith the kettle and to secure the best results it is placed at some little dis]- T n; s Mas PATEN g t, .gU'D'OLF ELY'BIA, OHIO.

taneez'below the flange 10. The jacket is provided with a flange 20 cut away on the inner edge at 21to form a recess and a seat 22 for the means 15. Suitable packing 23' is placedv on the seat'under the means 15, to seal the seam between the jacket and kettle and to soften the seat for the flange The flange QO is provided with a threaded bore 25 for a belt or screw 26, which extends through an opening 28 in a clamp 29 provided with a heel 30 resting on one'side'of th flange 20 and with a toe 31 engaging the upper-side of the flange 15. In the embodinient shown, a number of clamps 29 are employed, each engaging a portion of the flange 15. By using, a plurality of clamps the strain on theflange 15 is so localized as to eliminate entirely any danger of causing any strain upon the enamel. I

Of course, it will be understood that the clamps 99 may be varied in length .to suit each particular-.condition. For example, where the danger of injuring the enamel is increased, each clamp may be made smaller and the number of clamps employed thereby increased, or, forrougher work, the clamps may be longer than illustrated, thereby reducing the number employed. If, incasting the kettle, the flange 15 is warped, or in any other manner deformed, such unevenness can be taken care of by applying more or less pressure to the various clamps, avoiding the strain upon the kettle, whichwould result from the use of a continuous clamp endeavoring to press out the warp in the flange, and thereby placing strain on the kettle wall, which would inevitably crack or break the enamel. 'The seam between the flange 15 and the seat 22 may be made gas-tight. I prefer to place the flange 15 far enough below the flange 10 to permit the ready removal of the clamps29 and the bolts 26.

I have illustrated this embodiment and these particular details for the purpose of better describing my invention. I do not wish to be limited to such embodiment or such details, as it will be apparent to those skilled in the art that numerous and extensive departures may be made from the form and details of the embodiment shown without departing from the spirit of the invention. I

I claim g 1. In combination, a jacket provided with a flange about its mouth having an annular recess in the inner edge thereof forming provided With means to be employed in con- I a seat for a kettle flange, a kettleprovided with an annular flange on the outside Wall members, each provided With a heel resting upon the jacket flange, and a toe resting upon the kettle flange and means for drawing said clamps down upon said flanges to hold said kettle and jacket together.

2. In combination, a jacket provided With a seat, a kettle and mechanism for fastening the kettle and jacket together, including means on the. kettle resting on said seat and a plurality of clamps for clamping said means in said seat and attaching means for attaching the clamp to the jacket.

3. In combination, a acket and an enameled kettle and mechanism for connecting the kettle to the jacket comprising an annular flange on the outside of the kettle Wall and a plurality of clamps for clamping said flange to the'kettle, said clamps extending all around the kettle and jacket and means for fastening the clamps to the jacket.

4. In combination, a jacket and a kettle provided With an annular flange, clamping means for clamping the flange to the jacket, and devices for causing said means to exert different pressures at diflerent points about said flange.

5. In'combination, a jacket and a kettle necting the kettle to the jacket and mechanism to apply to said means different pres- Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of latents,

sures at different parts of said means to parts of said flange to clamp said flange to said jacket.

7. In combination, a jacket provided With a flange about its edge, saidflange having an annula recess in the inner corner thereof forming a seat for a kettle flange, a kettle provided With an annular flange on the outside'wall thereof and below the edge of the kettle, said flange fittingin said recess and resting on said flange seat, a plurality of clamp members, each provided with a heel resting upon the jacket flange and a toe resting upon the kettle flange and'independent means for drawing each clamp member down upon said flanges to hold said kettle and jacket together With different pressures on different parts of said flanges.

8. In combination, a jacket and an enameled kettle, mechanism for connecting said jacket and kettle together With a gas-tight joint, comprising an annular member and a plurality of devices for clamping said member With different pressures at different points, and thereby connecting the kettle and jacket together.

In Witness whereof, I have hereunto signzed .my name this 16th day of March, 191 I RUDOLF F. GOECKE.
